[0002] In today's era of rapid development of electronic devices, as device power continues to increase, the requirements for heat dissipation performance are becoming increasingly stringent. 80W power level devices generate a lot of heat during operation. If this heat cannot be dissipated in a timely and effective manner, the internal temperature of the device will rise sharply. This will not only reduce the performance of electronic components and shorten their service life, but may also cause device failure, seriously affecting the stability and reliability of the device.

[0003] Traditional die-cast metal casting 80W bottom covers have many problems in heat dissipation. Some bottom covers rely on simple heat sink designs with limited heat dissipation area, which cannot meet the heat dissipation requirements of high-power equipment, resulting in heat accumulation and high operating temperature of the equipment. Some bottom covers use heat dissipation materials with poor thermal conductivity and slow heat conduction speed, making it difficult to quickly transfer the heat generated by the equipment to the external environment, further aggravating the heat dissipation problem.

[0004] To address the aforementioned issues, we propose a die-cast metal casting 80W bottom cover. Utility Model Content

[0029] Structural Description:

[0030] 1. Bottom Cover Body: The bottom cover body is the core load-bearing structure of the entire 80W bottom cover. It is made of die-cast metal casting process and has good mechanical strength and stability. It provides the installation base for other components. Its internal space is rationally planned to accommodate key components such as support columns and heat pipes. Its external contour is adapted to the equipment and becomes an important part of the equipment's protective shell.

[0031] 2. Buffer pad: The buffer pad is installed on the upper surface of the bottom cover body and fits tightly against the bottom cover body. It is usually made of elastic material. When the equipment is subjected to external impact or vibration, it can play a buffering role, reduce damage to the bottom cover body and internal components of the equipment, and protect the integrity of the equipment. At the same time, the heat dissipation holes evenly distributed at the connection between the buffer pad and the bottom cover body also participate in the heat dissipation system of the equipment.

[0032] 3. Upper heat spreader: The upper heat spreader is located at the center of the upper part of the bottom cover body and is in direct contact with the heating element inside the equipment. It is made of a material with high thermal conductivity, which can quickly absorb the heat generated by the heating element and evenly distribute the heat to a larger area to avoid local overheating. It provides a stable heat transfer basis for the subsequent heat dissipation process and is the key starting point of the bottom cover heat dissipation system.

[0033] 4. Positioning Columns: The positioning columns are evenly installed on the surface of the bottom cover body and correspond to the side of the heat spreader. One end of each column passes through the positioning plate, which plays a role in accurately positioning the bottom cover. When the bottom cover is installed on the equipment, the positioning columns cooperate with the corresponding positioning structure on the equipment to ensure that the bottom cover is installed in the correct position, and to ensure the installation accuracy between the bottom cover and other parts of the equipment. This makes the overall structure of the equipment stable. The positioning columns are tightly connected to the bottom cover body and the positioning plate, and become an important component to ensure the accuracy of equipment assembly.

[0034] 5. Heat dissipation holes: The heat dissipation holes are located at the connection between the bottom cover body and the buffer pad, and are evenly distributed. Their main function is to accelerate the air circulation inside the bottom cover. After the heat generated by the equipment operation is conducted to the bottom cover body, some of the heat can be exchanged with the outside air through the heat dissipation holes, thereby assisting the heat dissipation process of the entire bottom cover, improving heat dissipation efficiency, and reducing the internal temperature of the equipment.

[0035] 6. Upper heat pipe: One end of the upper heat pipe is connected to the upper heat spreader and receives the heat dispersed by the upper heat spreader. Through its own good thermal conductivity, it transfers the heat to the connecting heat pipe, and then establishes a heat transfer path with the heat dissipation components at the bottom of the bottom cover, realizing the transfer of heat from the heat source of the equipment to the outside of the bottom cover. It plays a connecting role in heat conduction in the entire heat dissipation chain.

[0036] 7. Connecting heat pipe: The connecting heat pipe is located inside the bottom cover. One end is connected to the upper heat pipe, and the other end is connected to the ring heat pipe. Its function is to connect the upper and lower heat transfer paths, transfer the heat from the upper heat pipe to the ring heat pipe, so that the heat generated by the heat source of the device can be more comprehensively distributed to the heat dissipation fins for heat dissipation, optimize the heat dissipation layout of the bottom cover, and enhance the heat dissipation effect.

[0037] 8. Support Columns: The support columns are installed in a grid pattern at the center of the bottom cover body, providing strong internal support for the bottom cover body. They can resist external impacts and vibrations, prevent deformation of the bottom cover body, and ensure the structural strength of the bottom cover. The support columns have through holes inside, which reduces their own weight while ensuring support strength, achieving a lightweight design. The through holes can also assist in heat conduction, allowing heat to flow out along the through holes and participate in the overall heat dissipation process.

[0038] 9. Through-hole: The through-hole is located at the center of the support column and runs through the support column. Its existence reduces the weight of the support column, which helps to achieve the lightweight design of the bottom cover and reduce material costs. On the other hand, when the equipment is running, heat can be conducted through the through-hole, which accelerates the transfer and dissipation of heat inside the bottom cover, assists the heat dissipation function of the bottom cover, and improves heat dissipation efficiency.

[0039] 10. Ceramic Coating: The ceramic coating covers the surface of the bottom cover body and the positioning column. It has good heat insulation performance, which can effectively prevent excessive heat loss to the outside, keep the heat inside the equipment within a reasonable range for conduction and dissipation, and also has a certain auxiliary heat dissipation function to maintain the stability of the bottom cover's working temperature and improve the reliability of equipment operation.

[0040] 11. Ring heat pipe: The ring heat pipe is installed around the center of the heat dissipation fins and is connected to the connecting heat pipe. It further conducts the heat transferred from the connecting heat pipe to the heat dissipation fins. Through its own ring structure, the heat can be evenly distributed to all parts of the heat dissipation fins, which enhances the heat dissipation effect of the heat dissipation fins and plays a key role in heat distribution and transfer in the heat dissipation system of the bottom cover.

[0041] 12. Heat dissipation fins: The heat dissipation fins are fixedly installed at the lower end of the bottom cover body. They have a large surface area and a unique shape design. They can fully contact the outside air through heat convection and quickly dissipate the heat transferred from the inside of the bottom cover to the surrounding environment. They are the main components for heat dissipation of the bottom cover and play a vital role in reducing the temperature of the equipment and ensuring the stable operation of the equipment.

[0042] 13. Positioning plate: The positioning plate is fixed at the center of the bottom of the main body of the bottom cover. Its surface is provided with mounting grooves for installing heat dissipation fins. The positioning plate cooperates with the positioning column to accurately determine the position of the bottom cover on the equipment during the installation process, ensuring the matching accuracy between the bottom cover and other parts of the equipment, improving the equipment assembly quality, and ensuring the stable performance of the overall equipment.

[0043] 14. Lower heat spreader: The lower heat spreader is installed at the center of the bottom of the main body of the bottom cover, corresponding to the heat-generating elements inside the equipment (possibly receiving heat indirectly). Similar to the upper heat spreader, it uses its good thermal conductivity to evenly distribute the heat generated by the equipment. It works in conjunction with the heat dissipation components at the bottom of the bottom cover to provide a stable heat transfer foundation for the heat dissipation fins, etc., and further improve the heat dissipation effect of the bottom cover.

[0044] 15. Mounting slots: Mounting slots are evenly distributed on the surface of the positioning plate. Their shape and size match one end of the heat dissipation fins. They are used to fix the heat dissipation fins, so that the heat dissipation fins are firmly installed on the bottom cover body. This ensures that the heat dissipation fins are stable in position during heat dissipation and can perform their heat dissipation function normally. At the same time, they also participate in the structural connection system between the positioning plate and the heat dissipation fins, enhancing the overall stability of the bottom cover structure.

[0045] Instructions for use

[0046] Working principle: The heat generated during equipment operation is first transferred to the upper heat spreader 3 and the lower heat spreader 14. These two components utilize their good thermal conductivity to evenly distribute the concentrated heat, providing a stable foundation for subsequent heat dissipation. Simultaneously, the heat dissipation components on the surface of the bottom cover body 1 dissipate heat. The heat dissipation fins 12 dissipate heat through thermal convection and full contact with the air. The annular heat pipe 11 conducts heat from the lower heat spreader 14 to the heat dissipation fins 12. The connecting heat pipe 7 connects the upper heat pipe 6 and the annular heat pipe 11, enabling heat exchange between the upper and lower parts of the body, allowing for more comprehensive heat distribution to the heat dissipation fins 12. Furthermore, the heat dissipation holes 5 at the connection between the bottom cover body 1 and the buffer pad 2, the heat dissipation coating on the surface of the support column 8, and the heat dissipation coating on the bottom cover body 1 and the positioning column 4 all contribute to the overall heat dissipation. The ceramic coating 10 on the surface plays an auxiliary role in heat dissipation and heat insulation, maintaining the stable working temperature of the bottom cover. Multiple support columns 8 arranged in a grid pattern at the center of the bottom cover body 1 provide strong internal support to resist external impact and deformation. The through holes 9 inside achieve weight reduction and enhance the stable structure of the bottom cover. At the same time, heat flows out through the through holes 9 inside the support columns 8. The positioning columns 4 are evenly installed on the surface of the bottom cover body 1 corresponding to the side of the heat dissipation plate 3. One end passes through the positioning plate 13. The positioning plate 13 is fixed to the center of the bottom end of the bottom cover body 1 and is provided with an installation groove 15 for installing the heat dissipation fins 12. The two work together to accurately determine the installation position of the bottom cover and ensure the installation accuracy with other parts of the equipment.
